Synthesis and physico-chemical studies of heterometallic nitrilotriacetates of chromium(III) with some 3d metals . În: Chemistry Journal of Moldova, 2006, nr. 1(1), pp. 84-87.

Their chemical composition has been determined from the results of the elemental analysis and thermogravimetric study. The coordination modes of the nta3¯ ligand and the type of chemical bonds have been proposed basing on IR spectra.enheterometallicnitrilotriacetateschromium(III)3d metalsbipyridineArticle
